Heinze, Chicago, Ill., assigner to Victor Manufacturing & Gasket Company, Chicago, Ill., a corporation of Illinois Application March 8, 1935, Serial No. 10,054 v 4 Claims. (Cl. 288-1) This invention relates to an improved grease .original shaping, so as to produce a finished deretainer with oil splasher, and has for one of vice in conjunction with other associated parts. its principal objects a provision of means for seal- The housing is shaped as shown in the crossing oil or grease in a housing about a rotating section, with an outer periphery or rim I2 adapted shaft, and which, at the same time, includes what to embrace a reinforcing element, preferably in 5 is known as an oil splash ring. the shape of a washer I4, L-shaped in cross-sec- One of the important objects of this invention tion, as illustrated, which washer is of heavier is to provide an oil seal for rotating shafts, such material than the material of the shell, but prefas automobile axles or the like, and which, in aderably of the same metal, such as cold rolled dition to sealing the 'oil inside of the housing sheet steel. 10 and preventing leakage therefrom, either around The. washer is made heavier so as to reinforce theshaft or between the seal and the housing, the entire structure` and also to provide a good will also act to prevent the flowing or splashing pressed or driven fit against the interior of. the of any oil or grease which might be on the other axle housing, into which it is adapted to be inside of the seal and on the shaft, or which, vdue serted. It will be noted that the washer and shell 15 to some untoward circumstance, might possibly are joined together by spinning or turning down leak through the seal. the outer edge I6 of the rim I2 about the out- A still further object of the invention is to prcwardly faced edge or portion of the reinforcing vide a grease retainer with an oil splasher, which washer I4, and it will further be noted that the 0 oil splasher is integral with the structure of the washer I4 is of a larger inside diameter than the 20 grease retainer, and which device as a whole, isoutside diameter of thetshaft I8, so that there composed of a. minimum of. parts, while at the will not at any time be any contact between the same time affording a satisfactory and eicient washer I4 and the shaft. construction. Also positioned in the housing or shell I0 is a Another and'still further 'important object is pliant diaphragm 20, preferably of leather, L- 25 to provide a grease retainer or oil seal which shall shaped in cross-section, as shown, having one 1 include a pliant diaphragm of leather or the like, ange adapted t0 be held ih wiping 01 Oil-Sealing with means for normally holding a portion of the relationship with the shaft I8 by means of a consame against a rotating shaft in sealing relation- Vstrictingelement such as a garter Spring 01' the ship therewith, a mounting for the diaphragm, like 22. 30

In addition to securely showing the same as removed from the shaft. gripping the armored leather 20-24, the action As-shown in the drawing: of the inturned flange 30, in conjunction with The reference numeral I0 indicates generally the inwardly directed annular bead'or rim 28, the containing shell or housing of the improved is such that undesirable rotation of the ,armored 50 grease retainer of this invention, the same prefleather and its Splash ring 25 iS @liet/Wely Preerably comprising an open cup-shaped element, vented.

preferably composed of sheet steel or the like, It will be seen that herein is provided an oil which can be drawn or stamped into desired seal or grease retainer having an attached or shape, and whichcan also be worked after an practically integral splash ring which is simple of construction, composed of a minimum number of parts, and which, on account of its double-acting features, will be highly satisfactory in operation.

I am aware that many changes may be made and numerous details of construction varied throughout a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.

I claim as my invention:

1. A grease retainer comprising an outer shell, a reinforcing Washer therein, a, pliant diaphragm in the shell and a mounting for the diaphragm, said mounting comprising an armor positioned against one face of the diaphragm, and an oil splash ring integral with the armor and extending beyond the shell.

2. A grease retainer comprising an outer shell,4

a pliant diaphragm in the shell and a mounting for the diaphragm, said mounting comprising an armor positioned against one face of the diaphragm and an oil splash ring integral with the armor, said oil splash ring extending outwardly beyond the shell, the inner end of the armor being 'turned into clinching engagement with the diaphragm.

3. A grease retainer comprising an outer shell, a pliant diaphragm in the shell and a mounting for the diaphragm, said mounting comprising an armor positioned against one face of the diaphragm and an outwardly flared oil splash ring integral with the armor, said oil splash ring extending outwardly beyond the shell, the inner end of the armor being turned into clinching engagement with the diaphragm about its periphery.

4. A grease retainer comprising an outer open-ended shell, having an oiset shoulder and an annular bead formed in the oiset, a reinforcing washer positioned against the shoulder, an inturned ange at one edge of the shell for xing said reinforcing washer in position, an armored pliant diaphragm positioned against the said annular bead, said armor including an integral outwardly flared splash ring and an inturned flange at the corresponding end of the shell for xing said armored diaphragm and splash ring in desired position in the shell.
